At the same time, during the operation of the vehicle-mounted oxygen concentrator, the heat generated by the internal compressor increases the temperature of the oxygen concentrator, and directly adding an exhaust vent next to the compressor compartment cannot reduce noise.

[0030] Therefore, the existing vehicle-mounted oxygen concentrator compressor is easily damaged by bumps, and how to achieve good noise reduction while achieving cooling is a technical problem that urgently needs to be solved in this field.

[0038] The overall structure, working principle and technical effects of the oxygen concentrator 010 provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0039] The present invention proposes a compressor assembly structure and an oxygen concentrator 010; wherein, the oxygen concentrator 010 is formed by assembling various components in the compressor 400 assembly structure.

[0040] The compressor assembly structure proposed in the present invention includes a compressor compartment 200, which is located inside a shell 100; wherein, the bottom of the compressor compartment 200 and the inner bottom of the shell 100 form a ventilation cavity 102, a vent 201 is provided at the bottom of the compressor compartment 200, an air outlet 101 is provided at the bottom of the shell 100, and the ventilation cavity 102 connects the air outlet 101 and the vent 201; and the vent 201 and the air outlet 101 are staggered up and down to form a curved gas flow channel.

[0041] Furthermore, a mounting portion 150 is provided on the inner bottom wall of the shell 100, the ventilation cavity 102 is formed in the mounting portion 150, and the air outlet 101 is arranged in the mounting portion 150; the compressor compartment 200 is arranged on the mounting portion 150 through a connecting piece.

[0042] Please refer to Figure 1 The oxygen concentrator 010 provided by the present invention can be applied to a vehicle. By powering the oxygen concentrator 010 with the vehicle's power supply, a stable oxygen supply can be achieved inside the vehicle.

[0043] Of course, the oxygen generator 010 can also be used in various occasions in daily life.

[0044] Please refer to Figure 1 An oxygen concentrator 010 proposed in this embodiment includes a shell 100 and a compressor cabin 200. The bottom of the shell 100 is provided with an air outlet 101; a compressor 400 is arranged in the compressor cabin 200. The compressor cabin 200 is arranged inside the shell 100. The bottom of the compressor cabin 200 and the inner bottom of the shell 100 form a ventilation cavity 102. The bottom of the compressor cabin 200 is provided with a ventilation port 201. The ventilation cavity 102 communicates with the air outlet 101 and the ventilation port 201.

[0045] It can be understood that by providing a shell 100 with an air outlet 101 and a compressor compartment 200 with a vent 201, the compressor 400 generates heat during operation, and the hot airflow inside the compressor compartment 200 passes through the vent 201 and the ventilation cavity 102 and is discharged from the air outlet 101, thereby achieving cooling of the interior of the oxygen generator 010; by providing the ventilation cavity 102, the wind resistance of the airflow is reduced, and the airflow entering the ventilation cavity 102 is subjected to resistive silencing, thereby effectively reducing the noise of the compressor 400.

[0046] In this embodiment, the oxygen concentrator 010 includes a housing 100 .

[0047] An inner cavity is formed inside the shell 100 , and the structures related to the oxygen generator 010 are accommodated in the inner cavity of the shell 100 .

[0048] In this embodiment, please refer to Figure 1-Figure 2 The shell 100 includes a side panel, a first shell 110 and a second shell 120. The first shell 110 is arranged on the top of the second shell 120 and is fixed to the second shell 120; the first shell 110 and the second shell 120 are fixed and a cover plate 130 is installed on the front and rear sides thereof to form an inner cavity; wherein a functional panel 140 is also installed on the right side of the first shell 110 and the second shell 120.

[0049] For details, please refer to Figure 6The inner bottom wall of the second housing 120 is provided with a mounting portion 150 corresponding to the air outlet 101, and the compressor compartment 200 is arranged on the mounting portion 150 through a connecting piece. The mounting portion 150 is an annular structure, and the annular mounting portion 150 is provided with a groove, and the groove forms the ventilation cavity 102.

[0050] Please refer to Figure 2 and Figure 6 The air outlet 101 is disposed in the mounting portion 150 , and the air outlet 101 is a plurality of openings disposed longitudinally and arranged in sequence.

[0051] Optionally, a wind shielding rib structure may be provided in the mounting portion 150 to form a gas bending channel in the ventilation cavity 102, in which the gas flows and the wind resistance of the gas gradually decreases, thereby achieving resistant silencing of the airflow.

[0052] Optionally, see Figure 1 A handle structure 160 is also provided on the top of the housing 100 for the convenience of the operator in moving and carrying.

[0053] In this embodiment, the oxygen concentrator 010 includes a compressor compartment 200 .

[0054] In this embodiment, please refer to Figure 3 and Figure 4 The compressor compartment 200 is arranged inside the shell 100, and the compressor compartment 200 includes a mounting shell 210 and a base 220 in a rectangular structure. After the mounting shell 210 and the base 220 are connected and fixed by a connecting piece, the compressor compartment 200 is fixed on the mounting portion 150 by the connecting piece, wherein the base 220 and the mounting portion 150 form a ventilation cavity 102; the compressor 400 is installed on the base 220.

[0055] In this embodiment, please refer to Figure 6 The vent 201 is disposed on the base 220, and the vent 201 and the air outlet 101 are staggered up and down so that the vent 201, the ventilation cavity 102 and the air outlet 101 form a curved gas flow channel. When the vent 201 is opened on the rear side of the base 220 away from the air outlet 101, the air outlet 101 is located on the front side of the housing 100.

[0056] It can be understood that the vent 201, ventilation cavity 102 and air outlet 101 arranged in this way form a curved gas flow path, which increases the bending of the wind direction, increases the impedance of wind noise, thereby reducing sound reflection and effectively reducing the noise of the compressor 400.

[0057] In another embodiment, when the vent 201 is opened on the front side of the base 220 , the air outlet 101 is located on the rear side of the housing 100 .

[0058] In another embodiment, when the vent 201 is opened on the left side of the base 220 , the air outlet 101 is located on the right side of the housing 100 .

[0059] In another embodiment, when the ventilation opening 201 is opened on the right side of the base 220 , the air outlet 101 is located on the left side of the housing 100 .

[0060] Among them, the base 220 is also provided with sound-absorbing cotton.

[0061] It is worth mentioning that, because the car is often bumpy during driving, it is easy to cause damage to the compressor 400 of the vehicle-mounted oxygen concentrator 010, thus affecting its service life.

[0062] Therefore, in this embodiment, please refer to Figure 4 and Figure 5 At least four shock absorbing structures 230 are arranged on the base 220, and the bottom of the compressor 400 is connected to the at least four shock absorbing structures 230. The shock absorbing structure 230 includes a mounting seat 231 and a spring 232, one end of the spring 232 is fixed in the mounting seat 231, and the other end is fixed to the bottom of the compressor 400. It can be understood that by arranging the shock absorbing structure 230, the compressor 400 is damped to avoid collision with the compressor compartment 200.

[0063] Furthermore, in this embodiment, a buffer member (not shown) is provided on the inner wall of the mounting shell 210, and the buffer member can protect the compressor 400 from bumps and collisions, avoid noise generated by bumps and collisions, and also perform a partial sound insulation function.

[0064] Specifically, in order to provide optimal protection for the compressor 400 , buffer members may be provided around the inner wall and the top wall of the mounting shell 210 .

[0065] Wherein, the buffer component at least includes anti-collision cotton.

[0066] In this embodiment, the oxygen generator 010 includes a fan structure 300 .

[0067] The fan structure 300 is used to dissipate heat from the compressor 400 .

[0068] In this embodiment, an air inlet is provided on the left side wall of the mounting shell 210 of the compressor compartment 200, and the fan structure 300 is arranged on the mounting shell 210 relative to the air inlet and through a connecting member, and the air outlet end of the fan structure 300 is connected to the air inlet.

[0069] It can be understood that the compressor 400 is cooled by setting up the fan structure 300, and the air outlet of the fan structure 300 outputs airflow. The airflow takes away the heat generated by the compressor 400 and enters the ventilation cavity 102 from the vent 201. The ventilation cavity 102 reduces the wind noise of the airflow, thereby effectively reducing the noise generated by the compressor 400 and the fan structure 300.

[0070] Optionally, the fan structure 300 may be a heat dissipation fan.

[0071] In this embodiment, please refer to Figure 3 The oxygen concentrator 010 includes a solenoid valve 600 . The solenoid valve 600 is disposed on the left outer wall of the mounting shell 210 of the compressor compartment 200 , and the solenoid valve 600 is located below the fan structure 300 .

[0072] In this embodiment, please refer to Figure 3 and Figure 4 The oxygen concentrator 010 includes a compressor 400, wherein the compressor 400 is used to compress air. The compressor 400 sucks in gas and compresses it, and introduces the compressed air into the molecular sieve 500 through the solenoid valve 600 for separation.

[0073] In this embodiment, please refer to Figure 3 The oxygen concentrator 010 includes a molecular sieve 500, wherein the molecular sieve 500 is used to separate compressed air into oxygen and other gases. The air intake end of the compressor 400 extracts air and compresses it into high-pressure gas into the molecular sieve 500, and the molecular sieve 500 then separates the air into oxygen and other gases.

[0074] Specifically, the molecular sieve 500 is disposed on the rear outer wall of the mounting shell 210 of the compressor compartment 200 , and the air outlet end of the compressor 400 is connected to the air inlet end of the molecular sieve 500 .

[0075] Correspondingly, an oxygen exhaust port 103 is provided at the top of the first shell 110 of the shell 100, and the output end of the molecular sieve 500 is directly connected to the oxygen exhaust port 103 through a pipeline, so that oxygen is directly discharged into the vehicle.

[0076] The working principle and process of the oxygen concentrator 010 provided in the embodiment of the present invention are as follows:

[0077] The compressor 400 compresses the gas after sucking it in, and introduces the compressed air into the molecular sieve 500 through a pipeline for separation. The molecular sieve 500 separates the air into oxygen and other gases, and the oxygen is directly discharged into the external environment through the oxygen exhaust port 103.

[0078] The compressor 400 generates heat during operation, and the air outlet of the fan structure 300 outputs airflow to dissipate heat from the compressor 400. The airflow takes away the heat generated by the compressor 400, and the airflow enters the ventilation cavity 102 from the vent 201 to dissipate heat and reduce noise, and then is discharged from the air outlet 101.

[0079] In summary, the oxygen concentrator 010 and the compressor assembly structure provided by the embodiment of the present invention, by providing a shell 100 with an air outlet 101 and a compressor cabin 200 with a vent 201, when the compressor 400 is working and generates heat, the hot airflow inside the compressor cabin 200 passes through the vent 201 and the ventilation cavity 102 and is discharged from the air outlet 101, thereby achieving cooling of the interior of the oxygen concentrator 010; by providing the ventilation cavity 102, the wind resistance of the airflow is reduced, and the airflow entering the ventilation cavity 102 is subjected to resistive silencing, thereby effectively reducing the noise of the compressor 400.

[0080] Furthermore, the compressor 400 is directly cooled by providing a fan structure 300 .

[0081] Furthermore, by arranging a buffer on the inner wall of the mounting shell 210, the buffer can protect the compressor 400 from bumps and collisions, avoid noise generated by bumps and collisions, and also perform a partial sound insulation function.

[0082] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
